Why won't my Makita PLM4626 engine start?

  Joshua FrancisAug 7, 2025
  Several factors can prevent your Makita Lawn Mower engine from starting. It could be due to the throttle choke being incorrectly positioned, an empty fuel tank (fill it, consulting the engine owner's manual), a dirty air cleaner element (clean it, consulting the engine owner's manual), a loose spark plug (tighten to 25-30 Nm), a loose or disconnected spark plug wire (install it), an incorrect spark plug gap (set it to 0.7 to 0.8 mm), a defective spark plug (install a new, correctly gapped one, consulting the engine owner's manual), or a carburetor flooded with fuel (remove the air cleaner element and pull the starter rope until it clears, then reinstall the element). If none of these resolve the issue, the ignition module may be faulty, and you should contact a service agent.

  If your Makita Lawn Mower engine is hard to start or loses power, the issue might be due to dirt, water, or stale fuel in the tank. Try draining the fuel and cleaning the tank, then refill it with clean, fresh fuel. Another possibility is a plugged vent hole in the fuel tank cap, which you should clean or replace. A dirty air cleaner element can also cause these issues, so be sure to clean it.

  Abnormal vibration in your Makita Lawn Mower is often due to a loose or unbalanced cutting assembly. Try tightening the blade first. If the vibration persists, the blade may be unbalanced and require balancing.

  Doris PriceAug 20, 2025
  If your Makita Lawn Mower engine overheats, it could be due to restricted cooling air flow. Remove any debris from the slots in the shroud, blower housing, and air passages. Another cause may be an incorrect spark plug. Install an RC12YC spark plug and ensure the cooling fins are on the engine.

  elliottdavidAug 25, 2025
  An erratic running Makita Lawn Mower engine can stem from a defective spark plug. You should install a new, correctly gapped plug, consulting the engine owner's manual for specifications. Another potential cause is an incorrect spark plug gap; set the gap between the electrodes to 0.7 to 0.8 mm. A dirty air cleaner element may also lead to this issue, so clean it, consulting the engine owner's manual.

  If your Makita Lawn Mower engine skips at high speed, it is possible that the gap between the electrodes of the spark plug is too close. You should set the gap between the electrodes to 0.7 to 0.8 mm.
